[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. When lithium batteries are processed, they generally need to be coated and the pole pieces produced. After the pole pieces are produced, they need to be dried and compacted, and then cut.

[0003] At present, in the electrode cutting process, the electrode material needs to be initially cut horizontally, and then the cut electrode plate will be cut and formed again. In the process of horizontal cutting, since traditional equipment mostly cuts directly, and the electrode material is transported by loading rollers, the electrode material is in an uneven state when placed for cutting during the cutting process, which makes it impossible for traditional cutting equipment to cut accurately and effectively. Therefore, there is an urgent need for a electrode cutting device for battery processing. Utility Model Content

[0029] Furthermore, a coil spring 19 is provided at the connection between the connecting shaft 18 and the roller 10 .

[0030] In this embodiment, the raw material is introduced into the machine 1 by the feed roller 5, and in the process of continuous feeding, the raw material will move to the bottom of the support frame 3, and the cylinder 4 will be extended and retracted. The mounting frame 8 slides in the sliding groove 20 under the action of the cylinder 4, and the mounting frame 8 moves downward and drives the cutter 9, the roller 10, and the pressing plate 6 to move downward, wherein the roller 10 preferentially contacts the surface of the raw material under the action of the connecting arm 14, and the reverse force generated when the roller 10 contacts the surface of the raw material causes the connecting arm 14 to rotate in the connecting seat 13, and the connecting arm 14 is connected to the shock absorber seat 21 through the shock absorber 11.

[0031] At the same time, after the cutting is completed, the cylinder 4 moves upward, and the connecting arm 14 moves upward and is reset through the shock absorber 11. At the same time, the coil spring 19 begins to release the rewinding force, so that the roller 10 is reset.

[0032] In actual use, the connecting arm 14 rotates under the action of downward pressure, and the shock absorber 11 can ensure stability during downward pressure and provide an opposing force to ensure stable resetting.

[0033] In actual use, when the roller 10 contacts the surface of the raw material, the sliding rod 16 presses the spring 17, and the spring 17 provides an opposing force and improves the stability when in contact with the raw material.

[0034] In actual use, the cutting groove 7 can ensure the cutting stability.

[0035] In the utility model, the raw material is initially restricted by the feed roller 5, and when the cylinder drives the mounting frame 8 downward, the connecting arm 14 contacts the raw material and rolls on the surface of the raw material, and during the rolling process, the coil spring 19 enables the roller 10 to generate reverse power, and cooperates with the pressure plate 6 on the other side to effectively flatten the raw material and ensure that the surface of the raw material is flat, so that the cutting process is more precise and the cutting quality is effectively improved.
